hosted-engine --deploy fails on Ovirt-Node-NG 4.2.7
by Ralf Schenk 03 Dec '18

03 Dec '18

Hello, I try to deploy hosted-engine to a NFS Share accessible by (currently) two hosts. The host is running latest ovirt-node-ng 4.2.7. hosted-engine --deploy fails constantly in late stage when trying to run engine from NFS. It already ran as "HostedEngineLocal" and I think is then migrated to NFS storage. Engine seems to be deployed to NFS already: [root@epycdphv02 ~]# ls -al /rhev/data-center/mnt/storage01.office.databay.de:_ovirt_engine total 23 drwxrwxrwx 3 vdsm kvm 4 Dec 3 13:01 . drwxr-xr-x 3 vdsm kvm 4096 Dec 1 17:11 .. drwxr-xr-x 6 vdsm kvm 6 Dec 3 13:09 1dacf1ea-0934-4840-bed4-e9d023572f59 -rwxr-xr-x 1 vdsm kvm 0 Dec 3 13:42 __DIRECT_IO_TEST__ NFS Mount: storage01.office.databay.de:/ovirt/engine on /rhev/data-center/mnt/storage01.office.databay.de:_ovirt_engine type nfs4 (rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,clientaddr=192.168.1.121,local_lock=none,addr=192.168.1.3) Libvirt quemu states an error: Could not open '/var/run/vdsm/storage/1dacf1ea-0934-4840-bed4-e9d023572f59/2b1332f6-3bb6-495b-87fe-c5b85e0ac495/39d45b33-5f29-430b-8b58-14a8ea20fb08': Permission denied Even permissions of mentioned file seem to be ok.

Cannot remove old renamed hosted-engine storage domain
by Andrew DeMaria 03 Dec '18

03 Dec '18

Hi, I've been testing the hosted-engine restore process and have gotten stuck because I cannot remove the old hosted-engine storage domain. Here is the process I went through: 1. Setup two 70G luns under an iscsi target (one for the original, one for the restored hosted-engine. They are both empty at this point) 2. Install RHEL 7.6 on two other hosts (synergy and pointblank) 3. Install ovirt 4.2 on host synergy thru hosted-engine --deploy using one of the luns 4. Add host pointblank 5. Perform engine-backup and copy it off 6. Shutdown both RHEL hosts 7. Reinstall RHEL on both (wipe disk) 8. Install ovirt 4.2 on host synergy via hosted-engine --deploy --restore-from-file=backup.tgz using the other unused lun 9. Remove old host pointblank 10. Add host pointblank 11. Noticed that old hosted-engine storage domain (named hosted_storage_old_20181130T111054) is designated the master storage domain 12. Move storage domain hosted_storage_old_20181130T111054 into maintenance 13. Noticed that hosted_storage_old_20181130T111054 is still the master (even after moving it into maint while the new hosted_storage storage domain is healthy/active) 14. Tried to detach hosted_storage_old_20181130T111054 anyways, but presented with: Error while executing action: Cannot detach the master Storage Domain from the Data Center while there are other storage domains attached to it. -Please try to activate another Storage Domain in the Data Center. This is quite strange as the new hosted_storage storage domain is listed under that same Data Center named "Default" and is shown active. Any guidance would be much appreciated! Thanks, Andrew

hosted-engine deploy seems to be failed, but it is not
by Sinan Polat 03 Dec '18

03 Dec '18

Hi folks, A while ago I installed oVirt 4.2 on my CentOS 7.5 server. It is a single node. Everything is working, I can deploy VM's, etc. But it look likes that the hosted-engine is partly installed or something. [root@s01 ~]# hosted-engine --vm-status It seems like a previous attempt to deploy hosted-engine failed or it's still in progress. Please clean it up before trying again [root@s01 ~]# Any suggestions? Thanks! Sinan

cluster 4 pc's for more scanning power?
by Peter C. 03 Dec '18

03 Dec '18

Hello and sorry for the ignorance behind this question. I've been reading about various scale out, "hyper convergence" solutions and want to ask this about oVirt. I do vulnerability scanning on my company's assets. I do it from an obsolete laptop that was given to me. The load goes over 13 sometimes, and the scans take a long time. If I built an oVirt cluster from 4 or 5 desktop pc's, build VM to run OpenVAS, would the cpu load demanded by the scanning be spread accross the 3-4 hosts, not inlcuding the management host, and therby give my scans more CPU power? If not oVirt, is there another project that would be better suited to what I'm trying to achieve? Qualifiers: -I'm not asking if this is the best way to get high-load scanning done. I'm just asking if I'll get the combined power from the cpu cores of all the host machines. The scanning jobs thread already. -I know it would probably be more efficient to get a powerful multi core workstation or server to do this. That is not my question. -The pc's are perfectly good, they are just not being used and won't be used for anything else. Thanks in advance.

SPICE QXL Crashes Linux Guests
by Alex McWhirter 03 Dec '18

03 Dec '18

I'm having an odd issue that i find hard to believe could be a bug, and not some kind of user error, but im at a loss for where else to look. when booting a linux ISO with QXL SPICE graphics, the boot hangs as soon as kernel modesetting kicks in. Tried with latest debian, fedora, and centos. Sometimes it randomly works, but most often it does not. QXL / VGA VNC work fine. However if i wait a few minutes after starting the VM for the graphics to start, then there are no issues and i can install as usual. So after install, i reboot, hangs on reboot right after graphics switch back to text mode with QXL SPICE, not with VNC. So i force power off, reboot, and wait a while for it to boot. If i did text only install, when i open a spice console it will hang after typing a few characters. If i did a graphical install then as long as i waited long enough for X to start, then it works perfectly fine. I tried to capture some logs, but since the whole guest OS hangs it's rather hard to pull off. I did see an occasional error about the mouse driver, so that's really all i have to go on. As for the spice client, im using virt-viewer on windows 10 x64, tried various versions of virt-viewer just to be sure, no change. I also have a large amount on windows guests with QXL SPICE. These all work with no issue. Having guest agent installed in the linux guest seems to make no difference. There are no out of the ordinary logs on the VDSM hosts, but i can provide anything you may need. It's not specific to any one host, i have 10 VM hosts in the cluster, they all do. They are westmere boxes if that makes a difference. Any ideas on how i should approach this? VNC works well enough for text only linux guest, but not being able to reboot my GUI linux guests without also closing my spice connection is a small pain. as far as ovirt versions im on the latest, this is a rather fresh install. just set it up a few days ago, but i've been a long time ovirt user. I am using a squid spice proxy if that makes a difference.

UPS with USB Support
by florentl 30 Nov '18

30 Nov '18

Hi everybody, I'm currently setting up an ovirt solution. I have three servers with glusterfs. They run hosted engine. I configured the power management of the node for using idrac agent (I have Dell servers). The communication is ok but I don't really know if configuring power management is very usefull with only three servers. My three servers are powered via an ups which have only one usb port. I'm wondering what is the best option to shutdown the datacenter in case of power failure. I have read in previous posts that I have to write a script. So I think I'm going to : - install apcupsd on the node connected with the ups via usb - configure apcupsd.conf to lanch a script and send a mail - write a script to shutdown properly all the wm and to put the datacenter in maintenance mode What do you think about this solution ? Is there a better way to manage the vm's and datacenter's shutdown with the power management solution associated with ovirt host ? Regards, Florent

oVirt Node on CentOS 7.5 and AMD EPYC Support
by Tobias Scheinert 30 Nov '18

30 Nov '18

Hi, I am currently building a new virtualization cluster with oVirt, using AMD EPYC processors (AMD EPYC 7351P). At the moment I'm running oVirt Node Version 4.2.3 @ CentOS 7.4.1708. We have the situation that the processor type is recognized as "AMD Opteron G3". With this type of instruction set the VMs are not able to do AES in hardware, this results in poor performance in our case. I found some information that tells me that this problem should be solved with CentOS 7.5 --> <https://access.redhat.com/errata/RHEA-2018:1488> My actual questions: - Are there any further information about the AMD EPYC support? - Any information about an update of the oVirt node to CentOS 7.5? Greeting Tobias

About Windows guest agent
by Jingjie Jiang 29 Nov '18

29 Nov '18

Hi, I am new in oVirt and I'd like to get the clarification about the packages which support the function of Window guest agent from 4.2 release and how to build it. I looked through the document from ovirt.org, such as https://www.ovirt.org/documentation/internal/guest-agent/guest-agent-for-wi… It mentioned: /With the release of oVirt 3.5 we have introduced the oVirt WGT (Windows Guest Tools)./ // /The oVirt WGT provides an ISO with all the tools and drivers one needs to install on a Windows VM, with an easy to use installer to install it all in one step./ // /So manual compilation and installation of oVirt Guest Agent is no longer necessary./ // /The oVirt WGT ISO is included in //ovirt-guest-tools-iso-3.5-7.noarch.rpm <http://resources.ovirt.org/pub/ovirt-3.5/rpm/fc20/noarch/ovirt-guest-tools-…>//package./ Now, ovirt-guest-tools-iso is up to 4.2.4. I found the src rpm from https://resources.ovirt.org/pub/ovirt-4.2/rpm/el7/SRPMS/ovirt-guest-tools-i…, but I could not find ovirt-guest-tools-iso from github, only found ovirt-wgt. After clone the ovirt-wgt, I got the SPICE-tools-0.141.iso built. My question is : 1. Is ovirt-wgt used for Windows guest? 2. If so, how can I build ovirt-guest-tools-iso package or ovirt-tools-setup.iso Thanks, Jingjie // //

problems with aaa auth
by cmcl＠dneg.com 29 Nov '18

Hi, We've got problems authenticating using ldap accounts on the admin/vm portal. It reports: "Unable to log in. Verify your login information or contact the system administrator." We're running RHEV version 4.2.4.5-0.1.el7_3. I've tested ovirt-engine-extensions-tool using 'aaa login-user' with my profile name and a username and it auths fine. I can't find any log that might give a hint as to why it is failing. The ui.log is empty. It is also extremely slow (it spends a lot of time "waiting for cache..." just to load the administration portal, as well as to log in. Thanks for any help, Cam

AMD Threadripper support
by Darin Schmidt 29 Nov '18

29 Nov '18

My Issue is that there isnt an option to select anything other than Opteron based AMD chips. Is there a way to add my CPU to the list? I have an AMD 2970wx Threadripper. I found an article stating that you can edit the postre database. But where do I find the info needed to add a CPU to the list? Also when I tried to follow the instructions, I get: -bash-4.2$ /opt/rh/rh-postgresql95/root/bin/psql -h localhost -p 5432 -U engine -W /opt/rh/rh-postgresql95/root/bin/psql: error while loading shared libraries: libpq.so.rh-postgresql95-5: cannot open shared object file: No such file or directory

renewing 3rd-party certificate
by p.staniforth＠leedsbeckett.ac.uk 29 Nov '18

29 Nov '18

Hello, our system was using a certificate from a third-party CA that needed to be renewed. I created a CSR from the certificate and key, I replaced the certificate with the new one ( I also had to replace the CA certificate-chain). restarted the apache server but could no longer authenticate to our AD. I ran engine-setup, restarted the engine and also reinstalled the ROOTCA of our AD in the keystore. I got the system running but is there a documented procedure for updating 3rd-party certificates when authenticating to AD. Thanks, Paul S.

RAID L1/L5/L10 + NFS Loopback Benchmarks
by Andrei Verovski 28 Nov '18

28 Nov '18

Hi ! I run a series of benchmarks with IOZONE testing performance of different RAID configurations on HP ProLiant DL380 + impact of NFS loopback. NFS loopback is necessary even for very small systems (e.g. just 2 nodes), since oVirt local storage setup is limited to single (only one) node per data center and this is quite useless from the point of view of functionality. Full article: http://www.vacuum-tube.eu/wp/?p=537 Short YouTube slide show: https://www.youtube.com/watch?v=Xw_VN9G8jSI Related video: Moving away from local storage setup to NFS/GlusterFS https://www.youtube.com/watch?v=2ebhZ5U6x_Y

Re: AffinityGroup API

Can you please share the script? And also what's the permission of the user you are executing the script. When see error 'User is not authorized to perform the action', we print in engine.log, what's exactly wrong meaning we print what permissions the user is missing in order to execute that action. So it may help you find out what's wrong as well.

vGPU not available in "type mdev"
by Marc Le Grand 27 Nov '18

27 Nov '18

Hello I followed the tutorial regarding vGPU but it's not working, i i guess it's a Nvidia licence issue, but i need to be sure. My node is installed using the node ISO image. I just removed the nouveau driver ans installed the nVidia one. My product is : "GK106GL [Quadro K4000]" My driver is : NVIDIA-Linux-x86_64-390.87 In the host peripherals I see my card (pci_0000_05_00_0) listed, but the column "type mdev" is empty, as the doc says I should see vGPU i guess something is missing. I took a look, there seems to be nVidia vGPU copatible driver, but no trace of it. The only vGPU stuff i found it's "NVIDIA VIRTUAL GPU" and i understand I have to pay to use vGPU on my nVidia card. is this correct or no ? If i'm supposed to pay is there a free workaround ? thanks for your help marc

Hello I'd like to extract all vms which have the lease optionnal attribute and display the name of the storage domain of that lease.
